ELASTIC METAL SOLE.

To all whom it may concern:

Be it known that I, ULRICH ADANK BAU- MANN, a citizen of the SwissConfederation, residing at Lucerne, Switzerland, have invented certainnew and useful Improvements in Elastic Metal Soles, of which thefollowing is a specification.

The elastic metal soles of known construction have the disadvantage thatthey impede considerably the elasticity of the boots. I11 order to avoidthis inconvenience the metal sole according to the present invention ismade of metal plates which are con nected with each other by means of awire gauze.

In the accompanying drawing the invention is shown in two forms ofconstruction.

Figure 1 is a top view of a plate for elastic metal soles composed of anumber of metal rods which are connected by a wire netting. Fig. 2 is atop view of a plate for elastic metal soles composed of a number ofsmall metal plates which are connected by a wire netting.

According to Fig. 1 metal rods Z) are fixed upon a wire netting a whichis preferably made of steel wire. The soles c are stamped out of theplate thus formed along the outlines indicated in Fig. 1 by dottedlines.

According to Fig. 2 the sole is composed of a certain number of smallmetal plates cl which are connected by a wire netting a or the like.

The rods 1) and the plates d can be made of any suitable material butthey are preferably made of aluminium in consideration of the lightweight and of the other advantages of this metal. The metal rods orplates are fixed upon the Wire netting by pressing, it soft metal isused, or by $016181", ing or in any other suitable manner. A simplemanner for fixing the metal rods or plates upon the wire nettingconsists in' mounting pins at the side of the rods or plates which hasto come in contact with the wire gauze. hen the rods or plates and thewiregauze are submitted to pressure the pins become flat so that therods and plates are so to say riveted to the wire gauze. The distancebetween the adjacent metal rods or plates is only very small.

The edges of the soles 0 have to be fin.
